Abstract

We present the steps taken at the Combined Array for Research in Millimeter-wave Astronomy (CARMA) to handle the heterogeneous nature of the array, from apriori calibrations to data reduction. We outline the steps needed to track relevant variable quantities over time. We discuss methods for combining interferometric visibilities and single dish data in the context of single systems designed to obtain all the necessary data, potentially at the same time. Such an observing approach is available at CARMA and it is the intention of the Atacama Large Millimeter-submillimeter Array (ALMA) to offer this capability as a standard observing mode.
